[ion] 22047: - Get rid of the intriguing idea that exported/public APIs should have prototypes with inversed parameters (fix ObOpenObjectByName and all its callers). - Isolate ObFindObject into CmFindObject for the registry routines. Because of their well-known abuse of Ob, it's better to give them their internal routine so that when/if Ob ever gets fixed to parse properly, it won't force a re-write of Cm's object routines.

Log:
- Get rid of the intriguing idea that exported/public APIs should have prototypes with
inversed parameters (fix ObOpenObjectByName and all its callers).
- Isolate ObFindObject into CmFindObject for the registry routines. Because of their
well-known abuse of Ob, it's better to give them their internal routine so that
when/if Ob ever gets fixed to parse properly, it won't force a re-write of Cm's
object routines.
